The thin-walled tubular shaft shown in Figure 9.8 is made of a randomly oriented, short-fiber-reinforced metal matrix composite. The shaft has a longitudinal through-thickness crack of length 2a and is subjected to a torque T = 1 KN m. If the mode II fracture toughness of the composite is Kulc = 40 MPa m/2, determine the critical crack size for self-sustaining crack growth. T 2a T 38 mm 42 mm diameter diameter FIGURE 9.8 Thin-walled tubular composite shaft with longitudinal crack.
